Yellow-breasted Antpittas are generally encountered as solitary individuals, hopping along the ground or along fallen logs, pausing to probe into the soil or leaf litter. They seem less prone than some of the other smaller Grallaria to climb far above the ground.
There are no published data on territorial defense, maintenance, or fidelity for Yellow-breasted Antpitta.
Yellow-breasted Antpitta is presumed to be monogamous, but there are no specific data on pair formation or courtship. Adults sing from concealed perches, usually on or very near the ground.
Social and interspecific behavior
Little information; presumably is primarily solitary.
No specific data, but the only described nest of Yellow-breasted Antpitta was thought to have been destroyed before fledging (Greeney et al. 2009).
